Bernard, huh...here is a story of how to deal with Bernard.
********************
"Hey Bernard, we have a problem in the stern torpedo tube. Check it out for us."
"Jawohl, Herr Kaleun"
*Bernard crawls into tube*
"SEAL TUBE 5!"
"Sealed, sir!"
"Ready Tube 5!"
"Flooded and equalized, Sir!"
"Open Muzzle Door!"
"Tube 5 Ready, Sir!"
"Tube 5, LOS!!!!!!"
FWOOOSH!!!!
"Sir, was it necessary to launch the man out the tube?"
"Bernard was a problem. BdU has a saying when dealing with anything, especially a problem; Be more aggressive."
"I see, sir.

"
****************
That is what I would do with Bernard.
